You recorded your first course video four times. The lighting was wrong. You stumbled over a sentence. You heard yourself say “um” seventeen times. You gave up and never published the course.

If that sounds familiar, you’re not alone — and Synthesia exists specifically for this problem.

Synthesia is an AI video generator that turns a text script into a professional-looking video with a realistic AI avatar presenting it. No camera. No microphone. No editing timeline. Type your script, click generate, get a video.

In this deep dive, we’ll look at exactly how course creators on Teachable, Thinkific, and Kajabi are using Synthesia for online courses — which workflows it fits, where it falls short, and whether the pricing makes sense at each stage of your course business.

Why Course Creators Are Switching to AI Video

The course creation industry has a production problem. The barrier to publishing a course used to be knowledge and expertise. Now it’s video production.

Udemy, Teachable, and Thinkific all expect video-first courses. Students expect them too — a course with only PDFs and text modules feels dated compared to one with polished video lessons. But producing that video is genuinely hard:

• Camera anxiety is real. Many subject matter experts are brilliant but terrible on camera.
• Production costs add up. A freelance video editor costs $30–$100/hour. A one-hour course can take 20+ hours to produce and edit.
• Updates are brutal. If your course covers software, pricing, or regulations that change, re-filming and re-editing is a nightmare.
• Global reach requires translation. Reaching Spanish, Portuguese, or Mandarin speakers means either hiring voice actors for each language or losing those markets entirely.

AI video generators like Synthesia address all four problems simultaneously. That’s why course creators — especially those building B2B training, compliance courses, and software tutorials — are adopting them fast.

How Course Creators Use Synthesia: 5 Real Workflows

1. Lecture Videos (The Core Use Case)

The bread-and-butter use case for Synthesia course creation: replacing talking-head lecture recordings.

The workflow:

1. Write your lesson script in a Google Doc or directly in Synthesia’s editor
2. Choose an AI avatar from Synthesia’s library of 160+ avatars
3. Select a voice — Synthesia offers 140+ languages and dozens of voice styles per language
4. Add slides, screen captures (as images), or branded backgrounds if needed
5. Click generate — videos typically render in a few minutes
6. Export as MP4 and upload to Teachable, Thinkific, or Kajabi

A 5-minute lecture video takes roughly 30 minutes to produce from a finished script. Compare that to a full day of filming, editing, and color-correcting traditional video.

What works well: Concept explanations, frameworks, definitions, theory-heavy content, compliance topics, onboarding modules.

What doesn’t: Live software demos where you need to show a real interface in real time, hands-on coaching, or courses where your personal brand and face are the product.

2. Multilingual Course Versions

This is Synthesia’s killer feature for course creators with global ambitions.

Once you’ve built a course in English, Synthesia lets you generate the exact same video in Spanish, Portuguese, French, German, Mandarin, Japanese, or 130+ other languages — with the same avatar, the same visual style, and fully synced lip movements.

The workflow:

1. Translate your script (use a professional translator or AI-assisted translation tool)
2. Paste the translated script into the same Synthesia project
3. Switch the voice language setting
4. Generate a new video — the avatar’s lip movements automatically sync to the new language

This means a single course can be sold to English, Spanish, and Portuguese markets with maybe 2–3 hours of additional production work per language. Previously, this required hiring native-speaking voice actors (expensive) or asking your existing instructor to re-record in a second language (often impossible).

For course creators building B2B compliance training, HR onboarding, or software certification programs that need to ship globally — this feature alone justifies the cost of Synthesia.

3. Rapid Course Updates

Courses go stale. Especially courses covering:

• Software products with frequent UI changes
• Tax law, compliance regulations, or certifications
• Pricing pages, company processes, or product features
• Any “current” market data or statistics

With traditional video, updating a course means re-recording entire segments, re-editing, and re-uploading. With Synthesia, you just edit the script and regenerate. The avatar stays the same. The branding stays consistent. The only thing that changes is what the avatar says.

Real example: A software training course has a module on the pricing page. The product updates its pricing. With Synthesia, you update three sentences in the script and regenerate a 2-minute video. Total time: under 30 minutes. Total cost: a few minutes of your monthly plan allocation.

This alone is why corporate training teams — who maintain libraries of hundreds of videos — are heavy Synthesia users. See our roundup of the best AI video generators for corporate training for how Synthesia stacks up in that context.

4. Student Onboarding and Welcome Videos

Course creators on Teachable and Kajabi often struggle to make new students feel welcomed before their first lesson. A generic “welcome to the course” email doesn’t cut it.

Synthesia lets you create personalized-feeling welcome videos without filming yourself:

• A brief course overview video explaining what students will learn and why
• A “how to navigate this course” walkthrough using annotated screenshots
• Module intro videos that set context before each section

These don’t need to be long — a 60-90 second welcome video is often more effective than a 10-minute “about me” intro. Synthesia makes these quick to produce and easy to update semester-to-semester.

Pro tip: Use a consistent avatar across all your videos. Students will start to associate that avatar with your brand. Some course creators give their Synthesia avatar a name and build a consistent “host” identity around them.

5. Course Marketing Trailers

Getting potential students to click “Enroll” often depends on a compelling preview video. Most course creators skip this entirely because producing a polished marketing video feels overwhelming.

Synthesia makes it fast: write a 60–90 second trailer script that covers the course problem, the transformation, and a call to action. Pick your best-looking avatar. Add branded overlays or b-roll images. Export and upload to your sales page.

This isn’t the flashiest video production you’ve ever seen, but it’s dramatically better than no preview video — and preview videos consistently improve conversion rates on course sales pages.

Synthesia Pricing for Course Creators: Which Plan Do You Need?

Synthesia’s pricing page offers three main tiers relevant to course creators:

For new course creators: Start with Starter ($29/month) to validate whether AI video fits your style. Ten minutes/month is enough for 3–5 short modules or one complete welcome video sequence.

For active course creators: You’ll hit the Starter limit fast. Thirty minutes/month on Creator ($89/month) covers roughly 12–18 video lessons per month — enough to produce or update a full course in 2–3 months.

For corporate training: If you’re building compliance training libraries, onboarding programs, or certification courses with dozens of videos, the Enterprise plan’s unlimited minutes and custom avatar options become necessary. Custom avatars let you create an AI clone of a real instructor — one filming session, unlimited updates.

One important note: minutes reset monthly and don’t roll over. Plan your production calendar accordingly.

Synthesia vs. Alternatives for Course Creators

Synthesia isn’t the only AI video generator on the market. Here’s how it compares to the alternatives course creators most commonly consider:

HeyGen is Synthesia’s closest competitor and offers a very similar feature set. The main difference: HeyGen’s avatar quality is slightly better for short clips, but Synthesia has a more mature workflow for longer-form educational content and better LMS integrations. See our Synthesia vs. HeyGen comparison for a full breakdown.

InVideo AI is better suited for marketing videos and social content than educational course modules. Its template-first approach works well for short promotional content but feels limiting when you’re building a 12-module curriculum. See our Synthesia vs. InVideo AI comparison for more detail.

Loom is fundamentally a different type of tool — it records you (or your screen) via webcam. It doesn’t create AI-generated video. Loom is excellent for software walkthrough demos, quick async communication, and anything that genuinely needs to show a live interface. If you need screen recording alongside AI video, many course creators use both: Synthesia for lecture content and Loom for software demos.

Bottom line for course creators: If your primary need is talking-head lecture videos and multilingual content, Synthesia is the strongest option. If avatar aesthetics matter above all else, HeyGen is worth testing. If you mainly need screen recording with a webcam overlay, Loom is a better fit.

Synthesia for Teachable and Thinkific: Compatibility Notes

Teachable: Synthesia exports MP4 files that upload directly to any Teachable curriculum block. No plugins or integrations required. For advanced completion tracking, Synthesia’s SCORM export (Enterprise plan) is compatible with Teachable’s SCORM upload feature. Standard MP4 uploads work fine for most creators — SCORM adds quiz scoring and granular completion data if you need it.

Thinkific: Same story. Thinkific’s video lesson type accepts MP4 uploads, and Synthesia’s export quality is compatible. Thinkific’s “Video” lesson type is the standard home for Synthesia content.

Kajabi: MP4 upload to any Kajabi course post or video lesson. Kajabi doesn’t natively support SCORM, so the Enterprise SCORM feature isn’t relevant here — but for most course creators, direct MP4 upload is all you need.

LearnDash / Moodle: For WordPress-based LMS platforms, Synthesia’s SCORM export shines. These platforms natively support SCORM packages, enabling granular completion tracking across your video library.

Pros and Cons

✅ What Synthesia Gets Right for Course Creators

No production overhead. The single biggest advantage. You go from script to finished video in under an hour, no equipment required. For course creators who are subject matter experts but not videographers, this is transformative.

Consistent quality across your whole course. Every video has the same lighting, framing, audio quality, and production values. Real camera recordings vary wildly — your energy differs day to day, your background changes, audio quality fluctuates. Synthesia videos are consistent by design.

160+ avatars across demographics. Synthesia’s avatar library is large enough that most creators can find an avatar that feels right for their audience and subject matter. Corporate training courses have access to professional-looking avatars in business attire. Casual lifestyle courses can use more approachable-looking presenters.

Multilingual at scale. As covered above: this is the feature with no real competition. 140+ languages with proper lip-sync is genuinely unique at this price point.

Script-first workflow matches how most educators think. Writing first, presenting second, is how teachers naturally work. Synthesia’s workflow aligns with that.

❌ Where Synthesia Falls Short

AI avatars still look slightly robotic. The uncanny valley is narrowing, but it hasn’t disappeared. Avatars’ hand gestures feel repetitive. Eye contact can seem slightly off. For most viewers, this isn’t a dealbreaker — but it’s noticeable, and some audiences (particularly high-touch coaching clients) will prefer real video.

Not for personal brand courses. If you’re Tony Robbins, Marie Forleo, or a creator whose face IS the product — Synthesia won’t work. Students pay for you, not an AI avatar. Be honest about whether your audience is buying your content or your presence.

10-minute/month limit on Starter. Ten minutes of video sounds like a lot until you realize a typical course module runs 3–7 minutes. Starter is genuinely a trial plan. Most active creators need Creator ($89/month).

No screen recording. Synthesia is text-to-video only. If your course covers software, applications, or any live interface, you need a separate tool for those segments. This is a real gap.

Audio-only export isn’t offered. You can’t use Synthesia to generate just an AI voiceover — you get the video with the avatar. If you want AI narration over your own screen recordings, tools like ElevenLabs are better suited.

Frequently Asked Questions

Can I use Synthesia videos on Teachable or Thinkific?

Yes. Synthesia exports videos as MP4 files that you can upload directly to any course platform. For enterprise LMS platforms, Synthesia also supports SCORM export, which tracks completion and quiz scores.

How much does Synthesia cost for course creators?

The Starter plan is $29/month for 10 minutes of video. Most course creators need the Creator plan ($89/month) for 30 minutes. Enterprise plans offer unlimited minutes and custom avatars. Each plan resets monthly.

Do Synthesia videos look professional enough for paid courses?

For information-dense content like compliance training, software tutorials, and educational lectures — yes. The avatars are realistic enough for professional use. For personal brand-heavy courses where students expect to see YOU, stick with real video.

Can Synthesia create course videos in multiple languages?

Yes. Synthesia supports 140+ languages with native-sounding voice synthesis. You write the script in one language, and Synthesia can generate the same video in other languages with matching lip-sync. This is its killer feature for global course creators.

What’s the difference between Synthesia and just recording myself?

Time, consistency, and scalability. Recording yourself requires equipment, energy, and editing. Synthesia requires a script. For updates, Synthesia wins by a mile — changing 30 seconds of a video is a 5-minute text edit, not a re-recording session. The tradeoff: AI avatars can’t replicate your authentic personal presence.

Does Synthesia work for SCORM-compliant LMS platforms?

Yes, but only on Enterprise plans. SCORM export lets you package Synthesia videos into SCORM 1.2 or 2004 files compatible with platforms like LearnDash, Moodle, Absorb, and others. For Teachable and Thinkific, standard MP4 upload is sufficient for most use cases.

Verdict: Is Synthesia Worth It for Course Creators?

Rating: 8.8/10

For the right creator, Synthesia is one of the most efficient tools in the course production stack.

If you’re building information-dense training content — compliance, software, processes, certification, educational curriculum — and you’ve ever struggled with camera anxiety, production bottlenecks, or the cost of updating stale videos, Synthesia is worth serious consideration.

If you’re building a personal brand course where students are enrolling specifically because of you, your charisma, and your on-camera presence, Synthesia isn’t the right tool. No AI avatar replaces authentic human connection.

The multilingual capability is genuinely underrated. Course creators who can serve global markets with minimal additional production work have a real competitive advantage — and at $89/month, the cost of generating a full multilingual version of your course is negligible compared to hiring voice actors.

Who should try it:

• Subject matter experts who hate being on camera
• Course creators building multilingual content
• L&D teams maintaining large compliance or onboarding video libraries
• Creators who update content frequently and dread re-filming
• Anyone building B2B training courses at scale

Who should skip it:

• Personal brand coaches and creators whose face is the product
• Anyone who needs screen recording as the primary format
• Creators on tight budgets who only need occasional videos (Starter’s 10 min/month is limiting)

Synthesia offers a free trial with no credit card required. Given how fast you can produce a first video, it’s worth testing with an actual script from your course before committing to a paid plan.
